1000BASE-SX (3CSFP91), 1000BASE-LH70 (3CSFP97), 1000BASE-LX (3CSFP92), 1000BASE-T (3CSFP93) specifications

3Com Corporation has been a trailblazer in networking technology, providing a range of solutions designed to enhance communication and connectivity. Among its notable products are the 1000BASE series optical transceivers, comprising the 1000BASE-LH70 (3CSFP97), 1000BASE-LX (3CSFP92), 1000BASE-T (3CSFP93), and 1000BASE-SX (3CSFP91). Each of these transceivers offers unique features and specifications suited for various networking environments.

The 1000BASE-LH70 (3CSFP97) is designed for long-range applications, supporting distances up to 70 kilometers over single-mode fiber (SMF). Its laser technology enhances signal strength, facilitating long-distance communication without significant signal degradation. With a wavelength of 1310 nm, it operates efficiently in outdoor settings and is ideal for metropolitan and wide-area networks. This transceiver is especially valuable for enterprises needing to connect remote sites securely and reliably.

The 1000BASE-LX (3CSFP92) also supports long-distance connectivity, but its range extends up to 10 kilometers on SMF and approximately 550 meters on multimode fiber (MMF). This versatility makes it suitable for both intra-building links and longer inter-building connections. Operating at a wavelength of 1310 nm, it employs laser technology for high performance and reliability, making it a favorite choice for data centers and enterprise networks.

Next in the lineup, the 1000BASE-T (3CSFP93) is an essential module for those utilizing copper cabling. It offers the convenience of Gigabit Ethernet over standard Category 5e cabling, providing transmission distances of up to 100 meters. This transceiver caters to environments where fiber connectivity may not be feasible or necessary, making it ideal for simple networking setups in office buildings and local area networks (LANs).

Lastly, the 1000BASE-SX (3CSFP91) is optimized for short-range applications, supporting distances of up to 550 meters over MMF. Operating at a wavelength of 850 nm, this transceiver uses multimode fiber optics to deliver fast Ethernet connectivity, making it well-suited for data centers and high-bandwidth environments. Its cost-effectiveness and performance make it a preferred choice for short-distance networking tasks.

In summary, 3Com's 1000BASE transceivers—LH70, LX, T, and SX—provide organizations with a variety of options for establishing reliable and high-speed network connections. Each transceiver showcases specific features tailored to different networking needs, ensuring businesses can choose solutions that align perfectly with their requirements while facilitating seamless communication and data transfer.
